摘　　要：陈钢花，毛克宇等．利用地层微电阻率成像测井识别裂缝．测井技术，１９９９，２３（４）：２７９～２８１地层微电阻率扫描测井是９０年代成像测井技术的典型代表。所得的图像可以直观地显示出井壁地层的微细变化，可以对组成地层的岩石类型、岩石结构、沉积构造、裂缝等特征进行精细描述。尤其是能够有效地识别裂缝，指示裂缝的形态、位置、密度、闭合情况等。文章以胜利油田几口井的微电阻率图像（ＦＭＩ）为基础，通过岩心观测，提出用ＦＭＩ图像识别裂缝的模式。Formation Microscanner Log represents the imaging logging technology of 1990s. Its image shows intuitively the subtle changes of the formation at the sidewall and provides a highly detailed description of lithotypes, lithotextures, sedimentary structures and fractures. It can also indicate the shape, location, density and closure of fractures. On the basis of FMI images and core analysis from several wells in Shengli Oilfield, fracture identification modes by means of FMI images are proposed.
